• .net 对sftp服务器上文件的操作


    由于服务商从FTP服务器迁移到SFTP服务器,唉~~~,苦逼的我们就改来该去的吧。现在来稍微说说这个是怎么实现的。

    ----------------------------------------我是无耻的分割线------------------------------------------------------------

    就不赘述FTP和SFTP的区别了,只提一点在一定的程度上后者更安全,需要的同学请移步http://www.cnblogs.com/mfryf/archive/2013/05/29/3107286.html了解更多,谢谢!

    好了,既然要到服务器上去操作文件,我们首先要登陆服务器,就像登陆其他服务器一样,我们需要一个地址、用户名、密码,可能还需要一个端口号。

    这里我是借助于一个第三方的插件,SharpSSH 1.1.1.13,这是地址http://www.tamirgal.com/blog/page/SharpSSH.aspx(可以自行下载)。
